This magazine upgrade you will get additional rounds in the factory 10 and 12 round mags. These modifications are not permanent and easily install in minutes. This upgrade will increase your Smith & Wesson M&P 22 pistol magazine's capacity from the factory 10rd or 12rd magazines to 18 rounds. With one (1) in the chamber and 18 in the magazine, that's 19 rounds in the gun! The kit consists of magazine spring, Hi-Viz NicTaylor follower, black anodized aluminum basepad and hex wrench. This kit is NOT for the COMPACT M&P22. If you have the Compact pistol you can get the 16+1 Mag kit HERE

Please note you will not use the metal pin found in the factory follower. Most people use this pin to aid in loading the magazine. If you have the need for a load assist tool we have two options for you. The first uses the hole in the blue follower to push the follower down. You can find it HERE. The second works more like a traditional magazine loader and can be found HERE

We recommend using high velocity ammo for this kit. With so many rounds in the magazine, there is more pressure exerted on the bottom of the slide. This pressure is difficult to overcome as the slide attempts to cycle with the use of some low power ammo. Even with high velocity ammo, the slide may not lock back every time on the last shot fired.

5 of 5 Creates a Better Balanced Pistol. August 2, 2021
Reviewer: Ed Spring from Eugene, OR United States  
Simple modification to the magazine that creates not only a significant increase to capacity, but with the heavier and thicker baseplate, also gives you a better grip and balance.

4 of 5 Smith & Wesson M&P22 Pistol Mag Upgrade February 8, 2021
Reviewer: Ted Babiy from Devon, PA United States  
These do a nice job of increasing capacity from 10 or 12 to 18 rounds, advertized.  17 rounds is more realistic, but still a nice bump.

5 of 5 Mag + kits January 6, 2021
Reviewer: bikesrususa from America  
I have used several of these kits that will add rounds. The springs and followers work just fine. My latest order included a hefty mag base for the S&W M &P 22. I am delighted with the results.  The usually light 22 mags fall out of the magwell freely. Kits used include: the S &w m&p 22 fullsize and compact, a colt match 22, abd a ruger sr22. Give this stuff a try.
